In the last week and and half, your apartment has been flooded twice due to heavy rains. Water came up from underneath the poorly designed and installed floor boards settling even into the mat underneath the carpeting. Many people say that you should get the landlord to replace it, while others say you need a local upholstery commercial cleaning service. True, it probably needs a local inspector to check for mold first, but water has stained our carpets in several spots. Calling just the maintenance manager is not enough; you need a pros opinion and solution first. Calling several in your area, and they all say about the same things as each other. While extracting water with bleach to kill mold is not enough, replacing the musty, moldy carpets is a must. But how to do this in a quick fashion before going berserk and wreaking of this hideous odor are another. Local professional steam machines are only good for a while; you should probably accept the fact that you are need of a pro.
